Addition

About Addition practice

Addition is free online math practice focused on addition facts — not story problems or lessons.

This open addition page keeps range, digits, regrouping, and question type in one place. Change them here before the next session.

Progress stays on this device for each local player. Sign in later if you want those stats on another device.

What makes this page different

• Skill focus

  Open addition. Tune range (10–200), digits, and regrouping before you start. Questions use standard a □ b = ? facts.

• Number size

  Defaults use 1-digit numbers within 20. You can widen or narrow the range in settings before the next session.

• Regrouping

  This skill starts with mixed regrouping. Change regrouping in settings if you want a softer or harder set of facts.

• Open practice

  This open addition page can cover easier or harder facts. Change the range, digits, regrouping, and question type here.

Good times to use this skill

• Daily math practice for kids

  Use a short session of Addition after homework or as a morning warm-up. No account wall — open and start.

• Classroom centers

  Put Addition on a shared device with local players so siblings or classmates keep separate records during math practice.

• Build toward speed

  After accuracy looks solid on addition facts, switch to the timed speed challenge for math fluency practice under a clock.

How to practice Addition

1. Review the default difficulty for this skill, then change the settings this page still shows.
2. Press Start. Answer each fact with the number pad or keyboard.
3. Wrong answers can be retried on the same question (except when you move on after a correct submit).
4. Finish the set to see accuracy, median time, and missed facts. Retry missed or practice again.
5. Records stay on this device for each player. Sign in if you want those stats on another device.

Settings you can change

• Choose how many questions to answer in the session (or set a custom count).
• Turn on Show elapsed if you want a stopwatch without ending the session early.
• On the open addition or subtraction page, change the number range, digits, and regrouping. Within 10 hides regrouping.
• On the open addition, subtraction, multiplication, or division page, choose regular, missing number, or chain. Multiplication and division have no chain.
• Settings lock while a session is running, then apply on the next Start.

Tips

• Aim for accuracy first. Speed comes after the fact feels automatic.
• Use Retry missed after a session to weight the facts that were wrong.
• Check Stats to see weak facts and recent sessions for this player.
• On this page you can change regrouping. Within 10 has none, so that choice disappears.
• For timed math fluency, open the Speed challenge after a solid round of Addition.
